General Characteristics

Copper is a well-known plastic metal with a reddish-pink color. Technically pure copper in terms of impurities there are three main grades: M1 (contains 99.9% of pure copper), M2 ((99.7%), M3 (99.5%). The main advantage of copper — electrical and thermal conductivity depends not only on the copper grade (i.e. chemical purity), but also on the state of supply. For example, the electrical resistivity of products made of M1 grade is: 0.0179 ^Ohmxmm2/m for unannealed circles, 0.1 748 ^Ohmxmm2/m for annealed ones, for trolleys drawn from wire rod- within the range 0.1 755−0.1 770 ^Ohmxmm2/m, for annealed wire made of wire rod — 0.1 718−0.1 724 ^Ohmxmm2/m. The difference in electrical conductivity of different grades of copper = 2−3%, there is a similar difference between the resistance of annealed copper and hard copper. The most common types of rolled copper are sheets, rounds, strips, bands, tubes, wire, and bars.

Production

Wires and bars are produced hard and soft according to GOST 434−78 from M1 copper (GOST 859−2001), with admixtures not more than 0,1%.
Bars are produced according to GOST 434−78 of copper М1, М2 or М3 (GOST 859−2001) of round, square and hexagonal cross-section.
Manufacturing of tubes is regulated by GOST 617−90 from copper of M1r, M1, M2r, M3r, M3 grades with chemical composition according to GOST 859−2001. Copper tubes of L96 grade (GOST 15 527) are produced with higher and normal accuracy of measured and unmeasured length within the range of 1−6 meters. Tubes can be pressed, cold-deformed, soft, semi-solid and hard.
Sheet production is regulated by GOST 495−92 of M1p, M1, M2p, M2, M3p and M3 grades (GOST 859−2001). Strips and cold-rolled sheets are produced with increased and normal accuracy. Hot-rolled sheets are produced in accordance with GOST 495−92 in nominal and measured lengths 500−2000 mm. Bands and cold-rolled sheets are delivered semi-hard, soft and hard according to the state of material.

Copper sheet occupies a special position among copper rolled products. It is relatively inexpensive, highly ductile, easily stamped, resistant to moisture and temperature fluctuations. All these qualities make it the ideal material for roofing and facade work. Copper roofing is characterized by high aesthetic and performance qualities — over time it covers the noble patina, and it looks beautiful. Copper roof — extremely durable, does not need care, it does not affect the vagaries of weather or solar radiation.
